  • At a maximum, an f-orbital can hold_____ electrons, a d-orbital can hold_____ electrons and a p-orbital can hold ________ electrons.
    14, 10, 6
  • What element matches this electron configuration?
    Calcium
  • How many orbitals are there in energy level 4?
    s, p, d, f
  • All elements in the same PERIOD have what in common?
